A website that helps people cheat on their partners has reportedly been hacked.
According to The Impact Team, it has the details, naked selfies and sexual fantasies of 37 million people - one million of whom are Brits - on Ashley Madison.
In a message, they said: "We are the Impact Team. We have taken over all systems in your entire office and production domains, all customer information databases, source code repositories, financial records, emails.
"Shutting down Ashley Madison and Established Men will cost you, but non-compliance will cost you more: We will release all customer records, profiles with all the customers' secret sexual fantasies, nude pictures, and conversations and matching credit card transactions, real names and addresses, and employee documents and emails."
